Until a few decades ago, employment discrimination perversely strengthened our teaching force. Brilliant women became elementary school teachers, because better jobs weren’t open to them. It was profoundly unfair, but the discrimination did benefit America’s children.
These days, brilliant women become surgeons and investment bankers — and 47 percent of America’s kindergarten through 12th-grade teachers come from the bottom one-third of their college classes (as measured by SAT scores). The figure is from a study by McKinsey & Company, “Closing the Talent Gap.”
Changes in relative pay have reinforced the problem. In 1970, in New York City, a newly minted teacher at a public school earned about $2,000 less in salary than a starting lawyer at a prominent law firm. These days the lawyer takes home, including bonus, $115,000 more than the teacher, the McKinsey study found.
We all understand intuitively the difference a great teacher makes. I think of Juanita Trantina, who left my fifth-grade class intoxicated with excitement for learning and fascinated by the current events she spoke about. You probably have a Miss Trantina in your own past.
One Los Angeles study found that having a teacher from the 25 percent most effective group of teachers for four years in a row would be enough to eliminate the black-white achievement gap.
